3D Virtual Itinerary in the Geological Heritage from Natural Areas in Salamanca-Ávila-Cáceres, Spain

Abstract

From a large database generated from the geological heritage of more than 100 geosites in four natural areas of Salamanca, Ávila, and Cáceres provinces (Spain), the 13 most representative sites were selected, and their scientific, educational, and tourist/cultural interest values were determined. The natural park of Batuecas-Sierra de Francia-Candelario presents the highest values and is followed by the natural park of Arribes del Duero. Using geomatic tools, digital information was compiled from different thematic layers, and, together with photographs, diagrams, and descriptive cards, was incorporated to produce didactic resources. By interacting with digital information using the free Google Earth platform, 3D virtual flights, which can be followed in real time, were established and implemented in different formats (mpeg, avi, wma, etc.). These are reproducible in different multimedia systems, which increases the possibility of educational and tourism use by broad layers of the population. Therefore, this favors the sustainable development of the area.
